No go. The most useful link happens to never work: the et sdl audio link. I tried everything else on the page and nothing. Always with the same result: no such file or directory. Everything else with sound works just fine

I am gonna go out on a limb. Try, killall -9 pulseaudio
Once you are done playing fire it back up or reboot to get the sound back to the way it was.

Since it is a 32bit game and assuming you are on 64bits maybe grab alsa-lib.i686 alsa-oss.i686 etc etc. These are just guess's but as a Linux gamer myself I do know that pulseaudio is still the worse thing to ever happen to desktop Linux.

Now my only issue is getting kicked by PB. Even after manually updating.

Usually happens if it can't verify and update when you connect. Can't remember the solution for that - been long time. Just make sure you run the PB update in game directory to start with and check the PB log for the reason you were kicked. Good luck.
